The water supply for Herdecke Germany would be influenced by the Ruhr River and managed by the Ruhrverband corporation. In 1935, during the Nazi era, the organization was brought into line with Nazi ideology and placed under the authority of the Reich Office for Spatial Planning. Key infrastructure, such as the Hengsteysee reservoir, played a role in regional water management, with strict quality standards adhering to German drinking water regulation. The heavy Allied bombing of the city likely damaged the water supply.
Once the 75th Infantry Division captured any German city, they would have to establish water points to purify the water for the troops. The job of purifying water was critical. it was necessary test water being used by the troops and also testing was done on the city civilian water supply.
With the troops living so close to one another, the dangers involved in contracting a germ carried by water could result in catastrophe. Therefore to the men of the water points which were set up for the US Troops during the time spent overseas.
Water point signs were set up in each city leading to the purest water. The signs for the 75th Infantry Division were marked diamond, with an arrow pointing towards the freshwater supply.
On a small scale, American soldiers purified water using portable Halazone chlorine tablets for individual canteens. In this way, each soldier was responsible for purifying his own water supply. Halazone tablets were commonly used during World War II by U.S. soldiers for portable water purification, even being included in accessory packs for C-rations.
Engineer water supply platoons set up purification points near streams or ponds. For these larger scale water supplies, ERDLator Units were used. Technically named the “Water Purification Unit, Van-Type, Body Mounted, Electric Motor Driven unit, these were truck-mounted, van-type devices developed by the Engineer Research and Development Laboratory that performed flocking, filtration, and chlorination on water pumped out of local streams.
A passage from a field engineers manual points out the importance of the purification units: “One of the most important units was the water supply platoon. This platoon operated water purification plants called ERDLalators that could remove silt and suspended matter, filter, and purify even contaminated stream water. Producing from 1-3,000 gallons per day — the larger number was achieved using separate large rubberized settling tanks, one unit could adequately supply an infantry battalion under adverse conditions” Drinking impure water could be deadlier than a machine gun bullet.
What seems to have saved many World War II soldiers from disease was the popularity of coffee. As soon as the line of march stopped for more than a moment, the men would fall out and boil up some coffee.
Purified water is stored in large canvas tanks until forward military units need it. Unit tank trailers and 5 gallon metal storage cans are used to transport the water from the engineers water point to the troops. Every unit of 100 men or less is issued a water sterilizing bag, known as a lister bag. It is usually used to store and distribute water that has already been made fit for drinking. The bag can also be used to purify water when the water truck can not get to the front lines. The bag is made of heady duty canvas and can hold 36 gallons of water. It is hung from a tripod of poles or branches. Calcium hypochlorite was used to chlorinate and purify the water. Orthotolidine was used to test the water to see if it has been adequately chlorinated. A deep yellow color indicated that the water was safe to drink. It too3 0 minutes for the chemicals to kill any germs that were in the water.
These efforts, directed by the Corps of Engineers and Medical Corps, ensured safe drinking water in diverse theaters of operation. It was also used to supply fresh drinking water for the thousands of displaced persons who were released from forced labor camps.

The Ruhr River-Viaduct was opened in 1879 as part of the Düsseldorf-Derendorf–Dortmund South Railway, In May 1943, it was damaged by a flood wave following Operation Chastise (
The devastating floodwaters traveled down the Ruhr river, impacting several towns and villages downstream in the Ruhr Valley, including the area surrounding Herdecke Germany, which is situated on the Ruhr between the Sorpe dam and the Rhine. The flood wave swept away a pillar of the viaduct, narrowly missing an approaching train. The destruction caused massive, though temporary, damage to water, power, and industrial infrastructure in the region. Over 1,600 people died in the flooding, a significant portion being allied prisoners of war and forced laborers.
The Ruhr River was the final objective of the 75th Infantry Division. When the 75th reached this objective they had split the surrounded German troops in half and finally crushed the Industrial Ruhr Pocket. The Berger Memorial sits high on a hillside overlooking on a particularly beautiful section of the river Ruhr River between Wetter and Witten Germany. The memorial was built between 1902 and 1904 to honor Louis Constanz Berger, (1829-1891), an industrialist and community co-founder. Its construction occurred during a period of industrialization and modernization of the Ruhr region. I imagined that my father 1st Lieutenant Arthur Thorspecken and his C-Company might have come to this overlook to view their final objective. The memorial would have stood at this spot in April of 1945, having been built between 1902 and 1904,
During WWII, the Krupp steel works in Essen, led by Alfried Krupp from 1943, were the cornerstone of the Nazi war machine, producing artillery, tanks, and u-Boats. Despite massive Allied bombing, the works managed to remain standing until 1945. The firm heavily utilized over 100,000 forced laborers,
Düren is a quarter in Witten Germany just south of Dortmund. Rather than being a town, it is really just farm land. I parked on the side of a muddy farm road and hiked to a trail. That trail made its way along the edges of farm fields at the edge of the woods. A small stream separated the trail form the fields. I jumped the stream and set up to sketch at the edge of a farmers field. I worked quickly, but as I sketched it started to rain. The drops splattered on the page. A German woman was walking her dog on the trail She waved, but must have thought I was crazy to be sketching in the rain.
During the WWII, there were a total of around 24,900 forced laborers from all the occupied territories in the area now covered by the town of Witten. On average, they worked for approximately 15 months in the town, and made up the majority of the workforce there. At the beginning of 1945, for example, the forced laborers constituted about 55 % of the total workforce in Witten. The different areas of work that they performed meant that large-scale forced labor camps were needed. As a result, it is thought that between 230 and 250 forced labor camps of different sizes were established in the town during that period.
The 75th Infantry Division, 1st Battalion moved south with the other 2 Battalions against heavy last ditch German opposition on April 11th, 12th and 13th. My father, 1st Lieutenant Arthur Thorspecken lead C-Company as part of the 1st Battalion was part of this attack. They advanced towards Witten Germany and encountered stiff resistance as they neared the objective. They broke up a large scale counterattack with mortar and artillery fire. They then had to fight a fierce house to house battle through Witten to advance to the Ruhr River.
At the beginning of 1945, for example, the forced laborers constituted about 55 % of the total workforce in Witten. The different areas of work that they did meant that a large-scale accommodation was needed. As a result, it is thought that between 230 and 250 forced labor camps of different sizes were established in the town during that period.
Dorney Germany is a four road town just to the south of Dortmund. The 75th Infantry Division continued it’s attack south throughout April 9th and 10th with the 2nd Battalion capturing Oespel and Dorney then proceeding south to the regimental objective which ultimately would be the Ruhr river.
In entering one room in the Dortmund Forced Labor Camp, soldiers found 4 dead babies lying on a table covered with sheets. On the floor were naked skeletal men and woman also covered in sheets. Babies were systematically taken from Forced Labor women and then starved to death to satisfy the the German ideal of the final solution. If the woman did not get right back to work, she would be murdered as well. If a woman tried to recover her child from German custody, she would be shot.
It started to rain as I sketched. Rain drop blasts littered the surface of the sketch. I could not protect the page. I closed the sketchbook and sat as it rained, thinking it might stop. I was sheltered in a rain jacket. I finally gave up and put the sketchbook away. After walking half way out of the cemetery, the rain stopped. I went back to my spot and sketched again quickly. I managed to cover the page before another wave of rain started. As I was leaving, I noticed a headstone for Fritz and Gerta Torspecken. My last name is Thorspecken and in America that is quite unique. With just one letter missing, I thought these might be long lost relatives. I know that my original ancestor, Dr. Elias Julius Thorspecken emigrated to America in 1830 or so to build a new life. He served his new country as a doctor during the Civil War. Arolsen Germany the city that Augustus left, is just 142 miles due west. This headstone left me thinking that I might have deep roots in this area of Germany.
As Allied troops along with my father, 1st Lieutenant Arthur Thorspecken who was leading C-Company of the 1st Battalion of the 75th Infantry Division, were attacking Dortmund Germany and moving south, the German Gestapo were looking to hide atrocities before they retreated.
Hundreds of thousands of forced laborers were exploited in the armament factories and coal mines around the Ruhr River during the Second Word War. An estimated 30,000 forced laborers were deployed in Dortmund during the Second World War. They were accommodated in about 300 camps, one of those being a branch of the Buchenwald concentration camp.
In Dortmund Germany, I searched for an old building that might have stood back in 1945. The Altes Stadhaus was hosting a wedding when I stopped to sketch. People were gathered outside at the entrance to the building despite the intermittent rain. A woman released a metallic helium balloon and people cheered as the balloon floated up to the grey sky. I hunched over my drawing trying to block the rain before the page became a liquid mess. Saint Reynolds Church could be seen down the street.
On April 12, 1945, the 95th Infantry Division attacked attacked Dortmund from the southeast and liberating the central and southern part of the city. Edward D. Snell, in F-Company, 2nd Battalion, 378th Regiment, said he couldn’t believe how much of the city was destroyed by years of bombing. There was nothing left of the center municipality of Dortmund, it was completely gutted.
A dawn attack on April 8, 1945 resulted in the 75th Infantry Division capturing Kirchlinde and Marten Germany, cutting the rail lines leading into Dortmund, thus effectively isolating the city from the west. Marten is a district in western Dortmund, Germany, It is directly south of Kirchlinde.
The 75th Infantry Division freed thousands of Forced Laborers from Nazi Camps. Once freed, the laborers became known as displaced persons and it fell on the 75th Infantry Division to feed and care for them. If they fed the starving inmates too fast they would die. They then needed to send the displaced persons back east where they had been abducted and sent to German forced labor camps. The problem is that the displaced persons would be seen as traitors once they were sent back to Russia or Poland. Many would face certain death back east, or they would be treated as pariahs for the rest of their lives.
